DOOR-CHECK.

SPECIFICATION forming part of Letters Patent No. 363,688, dated May 24, 1887.

Application filed September 23, 1886. Serial No. 214,324. (No model.)

no improvement in detail, and then point out the novel features in a claim.

In the accompanying drawings, Figure l is a plan or top view of a door-check embodying my lmprovement, one portion of the same be- 1 5 ing shown as secured to a door and another portion to a door-casing. Fig. 2is a side view of 1 the same, looking toward the top of Fig. 1. Fig. 3 is a face View ofa portion of the doorcheck, a certain plate being removed.

A designates a portion of a door, and B a portion of a door-casing. In the use of my improvement a spring, as G, will usually be employed for closing the door.-

D designates a spring for-checking the move 2 ment of the door when closing too violently.

As shown, such spring consists of a piece of spring metal bent in-such manner as to have two arms, a a, extending approximately parallel with each other and a coil intermediate The arm a is secured in a socket. formed in a plate, D. It is so secured by means of a set-screw, b. It may be adjusted into different positions longitudinally. The plate D is adapted to be secured to the door- Pivoted upon a lug, c, on the plate D is a lever, E, provided with a camsurface, E. This lever may rock up and down on its pivot when necessary. A bumper, (Z, is shown as arranged in the plate D in such po- 0 sition that when the lever returns to its normal position after having been elevated a projection, 0, thereof will strike the bumper and prevent noise.

F designates a tappet mounted on the door A. 5 This tappet is mounted in a case comprising, as shown, two portions, ff. The screws which secure the case to the door pass through screw-holes in both portions f f, thereby securingsuch portions together. The tappet F is capable of a longitudnal movement within the case f f Its outwardly-extending end is provided with a horizontally-extending projection, g, which may be made integral with the tappet or secured therein in any suitable manner. The tappet is so placed upon the door that when the latter is closing the projection 9 will ride up over the cam'surface E on the lever E, and the tappet will thereby have a bodily movement imparted to it in the di reetion of its length. Its return movement to a normal position may be assisted by a spring, h, secured to the inner end of the tappet, and to the casing, if desirable. \Vhen the door is closing with a rapid movement, the tappet will, after passing the cam, strike against the arm a of the checking-spring, which thus constitutes an abutment for the tappet, and the movement of the door will be:arrested,because the tappet will not have time to drop below the arm a of the spring before coming in contact therewith. WVhen the door is closing slowly, and it is therefore unnecessary to check the movement of the door, the tappet will,after passing the cam, drop down beyond the cam before reaching the spring, the spring being far enough forward of the cam to admit of this. It will drop down sufiiciently far to pass heneath the arm a of the spring, and so permit the door to close. provement shown in Figs. 1 and 2, when the door is opened, the projection 9 upon the tappet comes in contact with the under side of the cam E, and rocks the lever upwardly, as de scribed, so that the tappet will pass below it. In the exampleshown in Fig. 1 the lever E is provided with two reversely-inclined cam-surfaces, one of which is shown in dotted outline. When the door is opened, the projection g rides up over the cam-surfaces,and so has alongitudinal movement imparted to it in its outward movement.

Ihaveshown the portion of the tappet which is adapted to come in contact with the checking-spring as provided with a rubber cushion or bumper secured in a socket in' the tappet by any suitable means. This cushion prevents noise upon the coming together of the tappet and spring.

In the example of my in I have shown the tap p et as arranged upon the door and the cam and checking-spring on the door-casing; but this arrangement could of course be reversed. The tappet also is shown as adapted to move vertically; but by dispos ing the parts upon the sides of the door and easing the tappet could be caused to move horizontally, the essential feature of my improvement being that the tappet shall have a bodilymovement in the direction ofitslength. When the tappet moves horizontally the le Ver E will preferably be returned to its normal position by a spring, 8. I have shown such a spring in dotted lines.

lVhat I claim as my invention, and desire I 5 to secure by Letters Patent, is-- The combination,with a door and door-casing, of a spring for closing the door, a tappet, a cam for imparting a bodily movement to the tappet in the direction of thelength of thelat- 2o tel and a checkingspring constituting an abutment for the tappet, substantially as specified.
